Simulate weekend days on public holidays

[wigster]

This is a bit of an edge case, but...

Frequently we're away from home for an extended period when there is a public holiday during the vacation. It's a bit strange when e.g. on Xmas day which happens to be a Wednesday the lights follow a standard Wednesday schedule instead of a weekend one.

For this sort of thing I am using the binary sensors from the workday platform, where you can have a sensor saying that in your jurisdiction you have a holiday today or there will be one tomorrow.

It would be great if the presence simulator had an option to simulate particular days of the week depending on the status of whether today is a holiday or tomorrow is a holiday -- usually some combination of last week's Friday/Saturday/Sunday.
